Title: Power supply switching device
Inventor: ITO ISAO
IPC: G01R29/18
Filed: 1990-10-26
Abstract: PURPOSE:To enable high-accuracy detection of an excessive current and phase interruption by constituting the device in such a way that first and second monitoring actions are alternately repeated, and when the currents of respective phases of a three-phase alternating current have exceeded a prescribed value, or when the current of one phase has gone down beyond a prescribed level than those of the other phases, the switches are turned off respectively. CONSTITUTION:The currents of respective phases of a three-phase alternating current continuously flowing in the closed condition of an electromagnetic switch 1 are detected by current detecting parts 21a to 21c, and these are monitored by a monitoring control part 23. The control part 23 carries out alternately first and second monitoring actions in a prescribed time cycle. In the first monitoring action, it is judged whether or not the current values of respective phases have exceeded a prescribed value, and when the condition exceeding the prescribed value continues, the switch 1 is turned off. In the second monitoring action, when the current of either one of three phases has gone down that the other phases and when such a condition has continued, the switch 1 is turned off. Thus, the presence of excessive current and phase interruption can be detected with high accuracy.
